.icAN-ILLING MCHINE.

To all 'whpom it may concern Be it known 'that I, WALTER which thefollowing is a specification.

-uid for which the machine is adapted.

-The resent inventionis an improvement upon tie'machine described in-application- No.664,829, for'can lling machine, tiled by me onlDecember.A 9, 1911.

The general principle of operation of the machine of thepresentinvention is like that of the machine ofthe said application,that i' is, can-sare provided each completely sealed I perforation inone oration is so small as to prevent spontaneous outiow of milk filled,can when. the can is inverted,

and the perforation is open. The filling of the milk intothe can iscaused by the insertion into the can of an air suction tube of IIiinuteldiameter and a milk conduit is brought into air sealed relation to theperforated head of the can`about the perforation, sothat there isestablished within the can a condition of subatmospheric pressurecausing the flow of milk into the can by the4 difference of pressureestablished within the can andthe exterior atmospheric ressure.` Thepresent invention is directet to mechanical improuements tending toadapt thel principles of the invention to commercial conditions 'anddemands of more extensive scope than would be made by the particular.machine set forth in the aforesaid appliexcept for a smallA fillinghead, which filling per from the cat-ion.

Before proceeding to azdescription of the mechanism, a brief outline ofthe conditions to be met will be given. It-is customary inv the canningof evaporated milk to employ three sizes of cans, vone of which is lmown,as thebaby can, the second ofwhich is known as the family can, and thethird of.

which is known as the tall can, while larger cans are also employed,but-not in such numbers as the sizes mentioned. Of the small types ofcans mentioned, many millions are annually produced, wherefore a minutesaving in the cost of production of each can-is very material in theaggregate. In order to bring such desirable result about I producethe'cans each completely sealed except for a small filling perforationin the center of one ofthe heads of the can, and such cans are placedupon the filling machine in the inverted .vposition, that is, with theperforated head downward, and at the completion of the filling operationthis perforated head still remains4 downward for a. time with theperforation freely open, so that .the perforation must be of so small asize that the milk or other liquid within the can will not spontaneouslyflow out of this small perforation, being resisted by the surfacetension of the liquid bridging the perforation. It is impractical tointroduce liquid into the can through so small a perforation through afilling tube' and consequently I have provided an air suction tube ofminute diameter which may be introduced into the can through the fillingperforation to the filling level and when a milk duct, which is pr0-vided, is brought into air tight relation to the perforated head of thecan about the perforation, air is at once withdrawn from the can throughthe air suction tubeand the milk is forced into the can by' the superiorexterior atmospheric pressure. The advantages of this mode of fillingcans are many, and one of the mst important advantages is that the smallperforation may be readily sealed after the can has been reinverted sothat the perforatedvhead is uppermost, by a small drop of solder, theperforation being so small that the surface tension of the melt edsblder will hold the solder in the perforation against dropping into thecan and in complete bridging relation to the p'erforation until thesolder has hardened, thus completing the sealin and in practice thissealmg may be per ormed expeditiously, and

with such certainty, thatit is only on veryV rare occasions that acan isimperfectly sealed. Because ofthe small amount'of solder employed, thesaving in this one item alone over thev employment of cans where cancaps are used, amounts .to many thousands of dollars annually, thishaving Vbeen demonstrated under actual commercial conditions. Thesuction method of filling the cans hasalso very material advantages,such as remaining automatically inactive should there be a failure intheplacing of the cans in`the machine,. or should a leaky can be placed inthe machine, and also contributes very materially to the simplificationof the structure. p

Because of the small filling perforation, it requires considerable timeto fill a can eventhough wit-h the inverted cans the filling may takeplace under pressure on =the milk farin excess of a permissible pressureexerted on, the milk 'through a filling tube into a non-inverted can,since under the lastnamed conditions foaming of the milk will occur.Because of the comparatively slow filling of the cans the machine mustbe correspondingly enlarged in order to accom-A eral extent..` At the'central portion of the' y pedestal are formed alined bearings 4, 5,respectively, 'these bearings being of suiiicient axiatextent to insuregood-bearing and wearing surfaces. The pedestal is connected to the base1 by bolts or screws 6 and at the upper end is-formed with a ball race 7in which are lodged antifriction balls 8, while resting on these ballsis a plate 9 having a. central liollowhub l0 adapted to the bearing 4,and the plate is provided with a ball race 11 adapted to receive theballs 8. Theplate 9 is thereforeY supported by the balls 8, whilebearing 4.

Carried by the plate 9 is a spider 12 secured to the plate by bolts orscrews 13 and formed with a central hollow hub 14, while lthe spider isprovided with 'radial-arms carrying at their outer ends a ring 15 havlngan inner circumferential upstanding flange 16. The ring is shown as asubstantially flat ring outstanding radially from theA portion providedwith the`flange' 16, the Vupper and lower surfaces of the rihg'beingsublv stantially parallel, although this is` not' obliguided by( the hubl0 in the Y gatory. At appropriate points the ring 15 I at one end forthe passage of the screw 50,

to permit limited adjustment, While at the,4 other end of this latchspring, which is in the form of a leaf spring, is bent. at an angle asshown at 53 to constitute a latch nose,

and from this angle portion there extends a tail piece 54 curved away'from the latch nose 53. The purpose of this latch Will appearhereinafter.

Adapted to rest on the plate 36 is a can receiving plate 55 having oneedge 56 curved on an arc struck from the axis of rotation of the spider,While the remainder of the edge of the plate is in part semi-circularWith terminal tangential portions, about which edge there is formed arib 57 Which in the installed inachinerises from the can receiving faceof the plate, and the rib 57 is of suoli radius as to form a stop for acan of appropriate size, such can being indicated at 58 in Figs. l, 4and 9. The plate has a central passage surrounded by a cylindricalaxially extended portion 59 terminating at the end remote from the platein an inturned Gange 60 defining a smaller opening 6l so that theextension 59 constitutes in effect a well open at the bottom. Adapted tothis well is a block 62 conforming in shape to the interior of the well,so that it may move axially thereof, being limited in downward movementby engagement with the flange or ledge 60. This block is of less lengththan the depth of the Well, but may move through the plate 55 above thecan receiving surface thereof. Extending axially through the block 62 isa passage 63 and at the ends of this passage the block has nippleextensions 64, 65, respectively, the extension 65 being closed at theouter end and provided with a central small passage 66 and a surroundingseries of passages 67, each for a purpose to be hereinafter described.The end of the block which may be termed the upper end, is formed withan axially inset channel 68 in surrounding relation to the nipple 65 andseated in this channel in closely Vembracing relation to the nipple 65is a ring gasket 69. Surrounding and carried by the nipple 64 is anotherring shapeq gasket 70 and this last-named gasket may, ,and preferably'is as compressible as the gasket 69, both of these gaskets beingpreferably made of soft rubber and both are of greater axial length thanthe nipples carrying them. Leading laterally from the passage 63 at an.intermediate point thereof is another passage 7l into which thereextends a pipe 72 to one side of and substantially parallel with thebore or passage 63 and close enough to the inner Wall of the Well tonecessitate the provision of a recess 73 in the flange 60 to accommodatethe pipe 72, this pipe and re cess coacting to prevent rotative movementof the block 62 in the well, but offering no '74, so that the canreceiving plate 55 may ne removed at any time and another like plaiesubstituted. If it be' assumed that the ma chine is adapted to cans ofdifferent heights and diameters, then the only change necesQ sary toadapt the machine to one size or the other of cans so far as thesupporting or carrying of the cans is concerned, is the substitution ofan appropriately sized plate 55 for the larger or smallerplate which mayhave been in use, and this is readily accomplished by the removal of thescrew 7 4, all the `)lates designed to initially receive the can beingprovided with Wells 59 of the same size. but the marginal flange 57 willbe less extensive for the smaller cans than for the larger cans, so thatthe can will always be centered with relation to the plate when placedthereulmm` ln Fig. 'll a small can 58a is shown in conjunction With aplate 55a in all respect-s like the plate 55 except that the iange 57 isof a curvature of less diameter than the i'iange 57 of the plate Eachcan or 5S is provided with a small central perforation 75 in one head,which in the operation of the machine must be brought into matchinglation with the passage 66 in the block 62, and this is accomplished bythe provision of an appropriate plate 55 or 55a agreeable to the can tobe filled. It tra-nspires.r however,

that a baby can is of materially less length than a tall can or a familycan, so that when a baby can is resting upon a plate 55a the other endof the can is too far distant from the plate 35, wherefore an adapter isprovided consisting of a block 76 having at one end a head 77 of a sizeto he engaged by the corrcspending head of the can 55%"11 and at theother end With a head 78 adapted to engage against the under face of theplate while a threaded stem 79 will then extend through the passage 44in the plate 35 and the pas sage 17 in the ring 15, and then a nut 8Oand Washer 8l applied to the threaded end of the stem 79 Will secure theadapter block 76 to the can basket. As will hereinafter appear, the head77 forms a relatively ixed member of a clamp for the can when the block76 is in place, While for the tall `cans the plate 35 performs the sameofice. When cans of different sizes are employed, other adjustments arelnecessary and provision is made for them, but these adjustments will bereferred to hereinafter.

The plug 124 has at one end an axial passage 127 ofsmall diameter and this passage is enlarged toward the other end toreceive packing 128, while atthe end of the plug provided With themilled head 125 the passage is still further enlarged and threaded toreceive an externally threaded plug 129 provided with a slot 130 for thereoeptiono a manipulating tool. Extending axially through the plug 121)is a small passage in line with the passage 12T, and these passages aredesigned to receive a tube 131 of a length to extend Yfrom the interiorof the passage 127 through the plug 121, thence through the passage G3to and through the passage (lli and when, as will hereinafter appear,the head 125 is brought into engagement with the gasket '70 and a cam 58is engaged by the gasket Gf), this tube 13.1 will extend through theperfora tion 75 into the can to a point adjacent the imperforate end ofthe can, such point coinciding with or closely approximating the fillinglevel of the can.

The block 118 has a lug or projection 132 extending from the boss 120 onthe side thereof opposite that communicating with the tube 117, and thislug has at one end a rounded portion 133 and at the other end a flatshoulder 134. The block 118 with the wings 119, boss 120 and lugI 132with the parts formed thereon may be all in one casting, and in order toprovide requisite strength Without undue weight the casting is providedwith strengtln-ning Webs Where needed. lVhile the block 11S is providedWith two wings 11S) on opposite sides of the tube 117, one ot the wings119 constituting the lower wing is designed to engage the block 43 andthis engagement limits the movement herein described of the block 118 inone direction, the movement in the other direction being limited in amanner to be described, the machine being designed to provide for amovement of the tube 131 to an extent to permit its introduction into aplaced inverted can to a predetermined limit, and its entirewithdrawalfrom the can. This movement is about an axis co incident with the centerof the ball 113 and While the relation of theipassages 112 and 116 maybe such that at one 'limit of movement 'of the block 118 these passagesmay be closed to eaoh other, it is necessary that at the other limit ofmovement the passages should he open tol each other. It is advis-- able,however, that the passages 112 and '116, should' be always incommunication whetherf rotor 'the tube 131 be within a can or Withdrawnthe losses due to the air entering the tubes 131 when performing noparticular function are negligible.

ln a con'nnerrial machine it becomes a practical necessity that theempty cans be fed automatically to the machine and the filled cansy be'taken automatically from the machine. For this purpose there isprovided a table lill; oi approlu'iate length for the support ot tendingand taire-away mechanismsL This table may be substantially straightalong the edge remote iroin the r0- tor, and along the edge adjacent therotor this table curved on an are struck from the center of rotation ofthe rotor, since the curved edge of' the table should be brought intoclose relation to the curved edges 56 of the can receiving plates 55 or55a as the case ma) be, wherefore the cans will easily slide on to theplates 35 or from these plates. The table 13G is supported substantiallyon a level with the upper iace of the can receiving plates ot the canbaskets by means ot' legs or rods 13T connected at their upper ends tothe table ucar the ends oi' the latter, and at their louer ends enteringsplit collars 13S on bracht-ts 1?)9 secured to and ol'setfrom theappropriate legs 53. The collars 138 are each supplie-d with a clampscrew 140 by means ot' which the respective leg 13T is gripped by thecollar in any appropriate position of adjustment.

At one and et' the table 136l there are provided spaced g ide strips111, 142, respectively, on oppf' te sides of a conveyor belt 143, thisbeit extending along the top of the table to a point where the guidestrips 141 and 142 are met by curved 4continuations 144, 144,respectively, made fast to the top of the table, and while Still inparallelv relation curving toward the outer edge of the untilsubstantially perpendicular thereto. The conveyer belt is carried beneat/i1 the strip 143, under a guard 145, and about a roller 116journaled on the under face of the table, from whence the belt returnsto the starting point. The strips 111-1 and 142, as Well as thecontinuations 1413 and 144, are of such height as to engage and guidethe cans while heilig carried hy the conveyor belt and while beingdirected therefrom to the can receiving plates 55 of the rotor. Theendet the cur'ued member 144 adjacent. the rotor is provided with a gate1417 constrained to assume a normal position by means of a spring 1-'18but yieldable to the passage of a mn. The eonveyer belt is run fasterthan the feeding of the cans upon the rotor so that there is always apushing tendency on the cans t hat have left the belt to move thempromptly into their places upon the rotor, but two' cans will not...move onto the Aroter at' a. time, since the' tangential por- Lozano?tions of the flanges 57 prevent such movement, Athese flanges being inclose side by side relation.

As the rotor carries the cans from the feeding devices, they are engagedsuccessively by spring controlled pivot fingers 149, 150, so positionedto hold the cans firmly against the curved portion of the flanges 57until the cans have become suitably clamped, as will hereinafter appear.Each finger 149 and 150 is mounted on the table 136 by means of a pivotscrew 151, and is'under the constant control of a spring 152, while apin 153 in the path of each lever limits its movement toward the can.

Depending from the table 136 is a bracket 154 carrying a throw-ofi cam155 designed as wil hereinafter appear to engage the tail pieces 54 ofthe spring latches 51. Extending from this throw off cam 155 in thedirection'of approachng cans is a safety bar 156 the purpose of whichwill hereinafter appear. 0n 'that part of the table 136 above the cam155 and har 156 is a takeoff mechanism comprising curved strips 157,158, respectively, the curved strip 157 terminating in a linger 159, solocated as to enback of a can located in a can basket, this fingerentering a recess 160 in the yoke 87 above the shoulder 47. The curvedmember 158 is so located as to be out-of the path of the cans white onthe rotor, but coacts 'with the curved member 157 to direct the cans ina curved path between guide strips 161 on the table 136 substantially inline with theguide strips 141 and 142, but extending in the oppositedirection therefrom. Between these guide strips the table is providedwith a shallow channel- 162, from which there leads a pipe 163 emptyinginto the reservoir 85, the purpose of which channel being to catch anydrip of mill: which may occur from the filled cans, although usuallythere is no suchl drip.

Depending from that portion of the table 186 correspond ing-to thereceiving end thereof, is a support 164 to which is connected one end ofa oar 165 by a collar 166,'in which the corresponding end of the bar 165is pivoted. The other end of this bar 165 is formed with an angleextension 167 passed through a bracket 168 fast to one of the supports137. The angle extension 167 carries a set collar 169 between which andthe bracket 168 the extension is surrounded KVAby a spring 17 O tendingto maintain the corresponding end of the bar 165 in an elevatedposition, the movement `lander -the action of the spring beingdetermined bya limiting pin 171 traversing the bar below the bracket168. Mounted. on the bracketv 168 is an other bracket" 1'72 npstandingtherefrom and can: ing a roller 173 close to that end of the ar 165provided with the angle extension 167. The bar 165 is set at an incline,

so that' the pivoted end supported by the 'collar 166 is lower thannthatendadjacent the roller 173.v The purpose of the bars 156- and 165 andthe cam 155 will appear hereinafter f Thepipe 30 and the pipe 26 arecontinued i stem 4prolongation is traversed by a pin 182 wlth itsvopposite ends in the path of two fingers 183 and 184,.'respectively,these pins being carried by the ring 15 on diametri.- cally oppositesides thereof, as indicated in Figs. 1 and 2 and Vone 'of these pins,nameiy, the pin 184, is shown in full lines in Fig. 14 and the rela-HV.;einen of the finger. 183 with respect en tip 182 is indicated. in dottedlines in'Fig. 14. Erom Fig. 13 it will be observed that the oppositeends of the pin 182 areldisposed at an angle one to the other indicatedat182 and 418%. Of course, it will be understood that the pin 182 may bein fact two pins.

The arrangement is such that when oneof the lingers, say the finger 184,engages the pin end .182, iffthat endbe standing upright a movement ofthe two valves 175 and 176 will be brought about causing the valves toopen to the atmosphere and close to v,the pipe l174, except thecontinuation of the pipe 174 between the valves, which continuation isdesignated "174% Under t-hese circumstances the valve 175f is placed inconv munication with the atmosphere and with the pipe 174 while thevalve 176 is placed in communication with a pipe 174a and also with theatmosphere through a spout 185, which spouty is -positioned to dischargeinto the reservoir 85. When" the movement of the valves just describedhas been brought about the pin end. 182r will be in an inclined positionwhile` the -pln end 182a will stand directly downward and inthe path ofthe finger 182, andwhenthisfinger engages the pin end 182 the valvslaremoved boekte' theoriginal position that the pipe'174 is continuous`through th pipegl74 .and ,communication withfthe atm 'fphere is ont o'.The lower end .ofthe pipgll maybe pro vided with a drainwalve'l l Theymachine thus describe will.` operate in the following manneitoll cans ofthe v'cha-I aeter ,setforth withanyfkind of liquid ,to whichthe-.rniacheisi-ada "ted,but as the .maohine is y .intended moreparticularly for .i'llingcanswith `milk of the' character known twovalves 175 and 176 Excellent results .moves the y 'from .thefeeding'mechansmfand the to the succeeding,

It is also assumed that there is a supply of cans ofappropriate size, say cans o8, which are indicated as of the tallvariety, and these cans are each wholly closed except that' in one headthere is a small central perforation 75.

mechanism, the latch 51 has already been disengaged in a manner to bedescribed from the nose 132 so that the block 118 has gravitated untilthe lower Wing 119 is in engagement with the block 43, the latter actingas a stop and supporting block. In this position of the parts the tube131 has its upper end about coincident with the top of the nipple 65 andWithin the passage 66 and, furthermore, the block 62 is resting upon theledge or flange 60 at the bottom of the well 59'. Since even in thisposition the tube 117 is in communication with the chamber 96 in turncommunicating through the pipes 97 with the hollow shaft 18 and so withthe exhaust mechanism, air is being drawninto they tube 131continuously, but so far as any action of the machine is concerned this"indrawing of airis inactive at this time.

As the rotation vof the spider continues, and considering but one canand'can basket with associated parts,the finger 132 engages on top ofthe bar 165 at the lower end of the latter, and since this bar isinclined, the block 118 is raised about the ball 113as a center, thetube 131 being thereby moved upwardly through thepassage 66 and into thecan through the perforation 75. While this is occurring, andparticularly While the tube 131 .is entering the can, the latter isengaged by the finger 149 and then by the finger 150, thereby holdingthe can firmly against the curved portion of the flange 57 of the plate55, so that the perforation 75 of the can is accurately centered withrelation 100 to the passage 66 and tube 131, Wherefore lthere is nodanger of the tube engagin the head of the can with such force as to endor otherwise injure the tube. The perforal 'tion 75 Which is produced bypunching, has 105 a slightly conicalform which aids in direct-v ing thefree end of the tube 131. As the rotative movement of the spiderprogresses,

.the finger 132 rides Astill fartheriup the vbar 165 until ultimatelythe head 125 of the 11o screw plug 124 is brought' into engagementWiththe gasket and then the block 62 is lifted as the risingmovement ofthe block 118 continues, and then finally'the gasket 69 engaging .theperforated head of the can 115 about the perforation lifts the can untilits imperforate and then upper end is brought into engagement with theplate 35 or in the case of the shorter cans, with the head 77, while theparts are so proportioned that-12o afterthis has occurred the block 118is raised still further, so that both gaskets are compressed, the gasket70 being c ompressed like the gasket 69, and the can is then z{rnilyclamped against the plate 35, or 125 "head 77 as the case may be. Whilethis con- .dition is being brought about, the? curved -portion 133 ofthe finger 132 engages the tail apiece 54 of the spring latch 51 carriedby the Lean basket in the path of the nose 132, and .18o

by the time the clamping has been effectively accomplished the shoulder134 has risen to an extent allowing the nose 53 of the spring latch tosnap under it, thereby locking a lock 118 in the raised position withthe can clamped between the plate or other resisting part, and the itsupper end is at. substantially the predetermined filling' level of the'can and the can is actually supported by the gasket 69 having beenlifted from the receiving plate 55 or .55a in accordance with the sizeof the can. The lat-ching of the block 113 in the raised ositiou isinsured by the presence of the roller 173', so located that as the block113 reaches its highest point and rides out of engagement with the bar165, the roller 173 forces the latch into locking position even if forsome ,reason its elasticity should not accomplish this result. Tolarities in the movement of the rotating parts, the bar 165 iselastically supported by the spring 1:70,v so as to give to excessiveforces, thus preventing at this point any liability of injury to themachine or to the cans. During this operation the exhaust has beenactive and as soon as the can is clamped and sealed about theperforation, air is extracted from the upper inner end of the can untilthere is produced within the can a condition of subatmospheric pressurewhich quickly reaches a point where the atmospheric pressure upon themilk within the reservoir causes a flow of milk\through the milk duct or.tube 'T2 into the passage 71 and from. thence into the passage 73through the passages' or pcrforations G7 intoA the space between thenipple and `the perforated headof the can Awhere surrounded by thegasket, and through the perforation into the can, the accumulating milkwithin the can preventing the formation of a stream of milk to an extentproducing the effect known as geysering and also clt'ect ualljiTpreventing foaming of the milk. The filling operation continues the canYunder consideration carried along'by the progressive rotative movementofg'the spider and. before the discharge end of the'machin'e which isadjacent the feeding end of'the machine has been rcacheththe can haslbecome filled with milk to the desired level and the milk begins tooverflow into the exhaust air or suction tube 131, and some milk findsitsl way through the air passages into the common exhaust chamber 9G andultimately into the shaft 13. v

The raising of the block G2 fo-r a limited distance to causeA theclamping ofthe can is participated in by the tube 72, but this movementis slight and immersion of thetube in the milk to a point near thebottom of the reservoir, so that at no time can :uilk foam reach vthemilk tube gasket 69, while the tube` V131 has projected into the `can'so that allow for irregu' does not affect the or duct, and consequentlynothing but liquid milk without a trace of foamcan reach the can, andpractical uniformity of filling is thereby insured.Y

The block 118 is maintained in the elevated position and the can in theclamped condition by the latch luntil the discharge end of the machineis approached, when the wing 54 of the latch 51 is engaged by the throwoff cam 155 and this cam is so shaped as to move the spring latchagainst its normal tendency until the nose 54 is withdrawn fromsupporting relation to the finger 132, whereupon the weight of the block11S and parts carried thereby causes a sudden dropping ofthe block aboutthe ball 113 as 'a center until this dropping movement is arrested bythe engagement of the lower wing 119 with the stop block 43. Thisfallingof the block 118 causes the withdrawal of the tube 131 quickly 'from thecan and at the. same time a breaking of the seal between :the gasket 69and the pe'rforated head of the can, also falls and t-he can drops untilagain 'supported by the-,plate 55'. The action is so quick that the tube131 is wholly withdrawn from the can while subatmospheric conditionsstill existwithin the space between the level of the milk within the canand the im 'pcrforate end ofthe can. The tendency to reestablish normalatmospheric conditions withinv the 'can causes an inrush of air throughthe perforation now out of sealing relation to the gasket 69 and lanyclinging milk which maybe about the perforation is drawn into the-canandthe perforation is left substantially clean. The seal is not quite soquickly' broken between the head 125 and the gasket T0 so thaty thereAis an opportunity for. milk to fallback throu h the tube or duct'72before'the seal at the gas {et 70 is broken, this milk ultimatelyreaching approximately to the level'of the milk in the reservoir. The.amount of milk which will drip from the lower end of the passage 64 'pthrough the gasket 70 where parts are so situated with reference to thereservoir thatsuch drip will find itsway into the reservoir, since theblock` 118 in the lowermost position slants toward the reservoir and thegasket 70 is immediately over the reservoir. The parts are so situatedthat the tube V131 is withdrawn from: thelled can and the can isuuclampcd before bei-ng engaged by the takeoff finger 159, so that thereis no resistance to the movement of the can from the plate v55 into .thespace between the guide Strips 157and 15S 'to theguide strips 161, bywhich latte'rvthe cans may be delivered to any .suitable place of`disposal. ln the further 'treatment o'f the cans after their rcmovalfrom-*the rotatable member of the unichine, these cansare-reiu\'ertedfso that the perforated end is uppermost and they maythen be sealed by the a plicatinof a single small drop f solder, te-,perforation being so small that the'surface tension of the meltedsolder does not permit the solder to flow through theaperforation intothe .cani to an extent to dropV therein inthe formof shot.` Sometimes asudden jar will cause an.' ,outflow-"of a drop 0f milk through theperforation,'whil e vthe can is traveling along -.i`nto the reservoir.
